DESCRIPTION OF CORNING CAPITAL STOCK

General
The following is a brief summary of certain provisions of the Restated Certificate of Incorporation of Corning (the "Restated Certificate") and does not relate to or give effect to provisions of statutory or other law except as specifically stated. The Restated Certificate authorizes the issuance of 500,000,000 shares of Corning Common Stock. As of September 22, 1994, 221,320,154 shares of Corning Common Stock were outstanding. The rights of holders of Corning Common Stock are governed by the Restated Certificate, Corning's By-Laws and by the New York Business Corporation Law (the "NYBCL").

Voting Rights
Subject to the voting of any shares of Series Preferred Stock (as defined below) that may be outstanding, voting power is vested in Corning Common Stock, each share having one vote.

Preemptive Rights
The Restated Certificate provides that no holder of Corning Common Stock or Series Preferred Stock shall have any preemptive rights except as the Board of Directors of Corning (the "Corning Board") may determine from time to time. No such rights have been granted by the Corning Board.

6


Corning Common Stock
Liquidation Rights. Subject to the preferential rights of any outstanding Series Preferred Stock, in the event of any liquidation of Corning, holders of Corning Common Stock then outstanding are entitled to share ratably in the assets of Corning available for distribution to such holders.

Dividend Rights and Restrictions. Subject to any preferential rights of any outstanding Series Preferred Stock and any outstanding preferred securities of Corning, such dividends as may be determined by the Corning Board may be declared and paid on Corning Common Stock from time to time out of any funds legally available therefor. Corning has regularly paid cash dividends since 1881 and currently expects to continue to pay cash dividends. Corning's current quarterly cash dividend is $.17 per share of Corning Common Stock. The continued declaration of dividends by the Corning Board is subject to, among other things, Corning's current and prospective earnings, financial condition and capital requirements and such other factors as the Corning Board may deem relevant.

Other Provisions. Corning Common Stock has no redemption, sinking fund or conversion privileges applicable thereto and holders of Corning Common Stock are not liable to assessments or to further call.

MIPS Offering
On July 21, 1994 Corning and Corning Delaware, L.P., a Delaware special purpose limited partnership in which Corning is the sole general partner, completed the offering (the "MIPS Offering") of $373.8 million aggregate principal amount of 6% Convertible Monthly Income Preferred Securities (the "Preferred Securities") of Corning Delaware.

Dividends on the Preferred Securities will be cumulative and will be payable monthly at an annual rate of six percent. In certain circumstances, holders of the Preferred Securities, voting as a class or by written consent, may cause the exchange of the Preferred Securities for shares of Corning's Series C Preferred Stock (herein defined), at a rate of one share of Series C Preferred Stock for every two Preferred Securities. Each Preferred Security is convertible at the option of the holder into Corning Common Stock at the rate of 1.2821 shares of Corning Common Stock for each Preferred Security (equivalent to a conversion price of $39.00 per share of Corning Common Stock), subject to adjustment in certain circumstances. From time to time after four years from the date of issuance, the Preferred Securities will be redeemable, at the option of Corning Delaware, in whole or in part, for cash at stated redemption prices. The Preferred Securities are subject to mandatory redemption on the 30th anniversary of the date of original issuance at a redemption price of $50 per Preferred Security together with accumulated and unpaid dividends (whether or not earned or declared). Holders of the Preferred Securities do not have any voting rights, except in certain instances of default.

Series Preferred Stock
The Restated Certificate authorizes the issuance of up to 10,000,000 shares of Series Preferred Stock, par value $100 per share (the "Series Preferred Stock"). The Corning Board has the authority to issue such shares from time to time, without stockholder approval, and the authority to determine the designations, preferences, rights, including voting rights, and restrictions of such shares, subject to the NYBCL. Pursuant to this authority, the Corning Board has designated 600,000 shares of Series Preferred Stock as Series A Preferred Stock, 316,822 shares of Series Preferred Stock as Series B Preferred Stock (the "Series B Preferred Stock"), and an as yet unspecified number of shares of Series Preferred Stock as Series C 6% Cumulative Convertible Preferred Stock (the "Series C Preferred Stock"). No other class of Series Preferred Stock has been designated by the Corning Board.

Series B Preferred Stock

Cumulative cash dividends at the rate of 8% per annum are payable on shares of the Series B Preferred Stock that have been issued. Corning has regularly paid dividends on the Series B Preferred Stock. No dividends may be paid or declared on the Series A Preferred Stock or Corning Common Stock unless all dividends for all prior dividend periods have been paid or declared on the Series B Preferred Stock, the Series C Preferred Stock and the Preferred Securities.

Holders of Series B Preferred Stock are entitled to vote, voting together with Corning Common Stock and not as a separate class, on all matters submitted to holders of Corning Common Stock, each share of Series B Preferred Stock having four votes, subject to adjustment.

Holders of Series B Preferred Stock have no preemptive rights. In the event of a liquidation, dissolution or winding-up of Corning, holders of Series B Preferred Stock shall be entitled to receive a distri-

7


bution in the amount of $100 per share, plus accrued and unpaid dividends, before any distribution on Corning Common Stock or Series A Preferred Stock.

The Series B preferred Stock is redeemable, in whole or in part, at the election of Corning, at any time, at the following redemption prices per share:

 During the Twelve-
Month Period               Price Per
Beginning October 1,         Share
1993                        $104.00
1994                        $103.00
1995                        $102.00
1996                        $101.00

and thereafter at $100.00 per share plus, in each case, accrued and unpaid dividends.

The Series B Preferred Stock is subject to redemption, at the option of the holder, at any time upon five business days' notice, at a redemption price equal to $100.00 plus accrued and unpaid dividends, if the proceeds are necessary (i) to make a distribution pursuant to an investment election made under the employee benefit plan or (ii) to satisfy any indebtedness to which the employee benefit plan is subject, provided that such payment is necessary to remedy or prevent a default under such indebtedness.

Corning, at its option, may make payment of the redemption price required upon redemption of shares of Series B Preferred Stock in cash or in Corning Common Stock, or in any combination of such shares and cash.

The Series B Preferred Stock is convertible at the option of the holder, at any time, into Corning Common Stock at a conversion price of $25.00 per share of Corning Common Stock, each share of Series B Preferred Stock being valued at $100 for the purpose of such conversion, producing a conversion ratio equal to four shares of Corning Common Stock for each share of Series B Preferred Stock so converted, subject to certain adjustments to prevent dilution.

Series C Preferred Stock

In certain circumstances, the holders of a majority of the aggregate liquidation preference of the Preferred Securities then outstanding, voting as a class or by written consent, may cause the exchange of the Preferred Securities for Series C Preferred Stock at a rate of one share of Series C Preferred Stock for every two Preferred Securities.

The terms of the Series C Preferred Stock are substantially similar to those of the Preferred Securities except that, among other differences, (i) in certain events of default, the number of directors of Corning shall be increased by two persons and the holders of the Series C Preferred Stock will be entitled to elect the persons to fill such positions and (ii) the Series C Preferred Stock will not be subject to mandatory redemption.

The Series C Preferred Stock ranks senior to the Corning Common Stock and the Series A Preferred Stock with respect to the payment of dividends and amounts on liquidation, dissolution and winding-up. In the event of a voluntary or involuntary bankruptcy, liquidation, dissolution or winding-up of Corning, the holders of Series C Preferred Stock are entitled to receive out of the net assets of Corning, but before any distribution is made on any class of securities ranking junior to the Series C Preferred Stock, $100.00 per share in cash plus accumulated and unpaid dividends (whether or not earned or declared) to the date of final distribution to such holders.

Preferred Share Purchase Rights
Attached to each share of Corning Common Stock is one Right, which entitles the registered holder to purchase from Corning one four-hundredth of a share of Series A Preferred Stock at a price of $62.50 per one four-hundredth of a share of Series A Preferred Stock (the "Exercise Price"), subject to adjustment. The Rights expire on July 15, 1996 (the "Final Expiration Date"), unless the Final Expiration Date is extended or unless the Rights are earlier redeemed by Corning.

The Rights represented by the certificates for Corning Common Stock are not exercisable, and are not transferable apart from the Corning Common Stock until the earlier of (i) ten days following the public announcement by Corning or an Acquiring Person (as defined below) that a person or group has acquired beneficial ownership of 20% or more of the Corning Common Stock (an "Acquiring Person") or (ii) ten busi-

8


ness days (or such later date as the Corning Board may determine) after the commencement or first public announcement of a tender or exchange offer that would result in a person or group beneficially owning 20% or more of the Corning Common Stock (the earlier of such dates being called the "Distribution Date"). Separate certificates for the Rights will be mailed to holders of record of Corning Common Stock as of such date. The Rights could then begin trading separately from Corning Common Stock.

Generally, in the event that a person or group becomes an Acquiring Person, each Right, other than the Rights owned by the Acquiring Person, will thereafter entitle the holder to receive, upon exercise of the Right, Corning Common Stock having a value equal to two times the Exercise Price of the Right. In the event that Corning is acquired in a merger, consolidation, or other business combination transaction or more than 50% of Corning's assets, cash flow or earning power is sold or transferred, each Right, other than the Rights owned by an Acquiring Person, will thereafter entitle the holder thereof to receive, upon the exercise of the Right, common stock of the surviving corporation having a value equal to two times the Exercise Price of the Right.

The Rights are redeemable in whole, but not in part, at $0.125 per Right at any time on or prior to any person or group becoming an Acquiring Person. The right to exercise the Rights terminates at the time that the Corning Board elects to redeem the Rights. Notice of redemption shall be given by mailing such notice to the registered holders of the Rights. At no time will the Rights have any voting rights. The Rights Agent is Harris Trust and Savings Bank (the "Rights Agent").

The exercise price payable, and the number of shares of Series A Preferred Stock or other securities or property issuable, upon exercise of the Rights are subject to adjustment from time to time to prevent dilution (i) in the event of a stock dividend on, or a subdivision, combination or reclassification of, the shares of Series A Preferred Stock, (ii) upon the grant to holders of the shares of Series A Preferred Stock of certain rights or warrants to subscribe for or purchase shares of Series A Preferred Stock at a price, or securities convertible into shares of Series A Preferred Stock with a conversion price, less than the then current market price of the shares of Series A Preferred Stock or (iii) upon the distribution to holders of the shares of Series A Preferred Stock of evidences of indebtedness or assets (excluding regular periodic cash dividends paid out of earnings or retained earnings or dividends payable in shares of Series A Preferred Stock) or of subscription rights or warrants (other than those referred to above).

The number of outstanding Rights and the number of one four-hundredths of a share of Series A Preferred Stock issuable upon exercise of each Right are also subject to adjustment in the event of a stock split of, or stock dividend on, or subdivision, consolidation or combination of, Corning Common Stock prior to the Distribution Date. With certain exceptions, no adjustment in the exercise price will be required until cumulative adjustments require an adjustment of at least 1% in such exercise price.

Upon exercise of the Rights, no fractional shares of Series A Preferred Stock will be issued (other than fractions which are integral multiples of one four-hundredth of a share, which may, at the election of Corning, be evidenced by depositary receipts) and in lieu thereof an adjustment in cash will be made.

The Rights have certain anti-takeover effects. The Rights may cause substantial dilution to a person or group that attempts to acquire Corning on terms not approved by the Corning Board, except pursuant to an offer conditioned on a substantial number of Rights being acquired. The Rights should not interfere with any merger or other business combination approved by the Corning Board since the Rights may be redeemed by Corning at $.125 per Right prior to the fifteenth day after the acquisition by a person or group of beneficial ownership of 20% or more of the Corning Common Stock (subject to certain exceptions).

The shares of Series A Preferred Stock purchasable upon exercise of the Rights will rank junior to all other series of Corning's preferred stock (including the Series B and Series C Preferred Stock) or any similar stock that specifically provides that they shall rank prior to the shares of Series A Preferred Stock. The shares of Series A Preferred Stock will be nonredeemable. Each share of Series A Preferred Stock will be entitled to a minimum preferential quarterly dividend of $10.00 per share, but will be entitled to an aggregate dividend of 100 times the dividend declared per share of Corning Common Stock. In the event of liquidation, the holders of the shares of Series A Preferred Stock will be entitled to a minimum preferential liquidation payment of $100 per share, but will be entitled to an aggregate payment of 100 times the payment made per share of Corning Common Stock. Each share of Series A Preferred Stock will have 100 votes, voting together with the Corning Common Stock. In the event of any merger, consolidation or other transaction in which Corning Common Stock is exchanged, each share of Series A Preferred Stock will be entitled to receive 100 times the amount and type of consideration received per share of Corning Com-

9


mon Stock. These rights are protected by customary antidilution provisions. Because of the nature of the Series A Preferred Stock's dividend, liquidation and voting rights, the value of the interest in a share of Series A Preferred Stock purchasable upon the exercise of each Right should approximate the value of one share of Corning Common Stock.

The foregoing description of the Rights does not purport to be complete and is qualified in its entirety by reference to the description of the Rights contained in the Rights Agreement, dated as of July 2, 1986 between Corning and the Rights Agent, as amended by the Amended Rights Agreement, dated as of October 4, 1989, which has been previously filed with the Commission.

Corning's Fair Price Amendment
In 1985 Corning's stockholders adopted an amendment (the "Fair Price Amendment") to the Restated Certificate that, in general, requires the approval by the holders of at least 80% of the voting power of the outstanding capital stock of Corning (other than the Series C Preferred Stock) entitled to vote generally in the election of directors (the "Corning Voting Stock") as a condition for mergers and certain other business combinations with any beneficial owner of more than 10% of such voting power unless (1) the transaction is approved by at least a majority of the Continuing Directors (as defined in the Restated Certificate) or (2) certain minimum price, form of consideration and procedural requirements are met. Certain terms used herein are defined in the Restated Certificate.

Amendment or repeal of this provision or the adoption of any provision inconsistent therewith would require the affirmative vote of at least 80% of the Corning Voting Stock unless the proposed amendment or repeal or the adoption of the inconsistent provisions were approved by two-thirds of the entire Corning Board and a majority of the Continuing Directors.

Certain Other Provisions of Corning's Restated Certificate and By-Laws In addition to the Preferred Share Purchase Rights and the Fair Price Amendment, the Restated Certificate and By-Laws contain other provisions that may discourage a third party from seeking to acquire Corning or to commence a proxy contest or other takeover-related action. Corning has classified its Board such that one-third of the Corning Board is elected each year to three-year terms of office. In addition, holders of Corning Common Stock may remove a Director from office at any time prior to the expiration of his or her term only with cause and by vote of a majority of holders of Corning Common Stock outstanding. These provisions, together with provisions concerning the size of the Corning Board and requiring that premature vacancies on the Corning Board be filled only by a majority of the entire Corning Board, may not be amended, altered or repealed, nor may Corning adopt any provisions inconsistent therewith, without the affirmative vote of at least 80% of the Corning Voting Stock of Corning or the approval of two- thirds of the entire Corning Board.

Corning's By-Laws contain certain procedural requirements with respect to the nomination of directors by stockholders that require, among other things, delivery of notice by such stockholders to the Secretary of Corning not later than 60 days nor more than 90 days prior to the date of the stockholders meeting at which such nomination is to be considered. The Corning By-Laws do not provide that a meeting of the Corning Board may be called by stockholders.

The Restated Certificate provides that no director will be liable to Corning or its stockholders for a breach of duty as a director except as provided by the NYBCL.

The effect of these provisions may be to deter attempts either to obtain control of Corning or to acquire a substantial amount of its stock, even if such a proposed transaction were at a significant premium over the then-prevailing market value of the Corning Common Stock, or to deter attempts to remove the Corning Board and management of Corning, even though some or a majority of the holders of Corning Common Stock may believe such actions to be beneficial.

PLAN OF DISTRIBUTION

The Shares are being sold by the Selling Stockholders for their own accounts. Except for the following limited circumstance, Corning will receive none of the proceeds from the offering. For the purpose of securing the indemnification obligations of the Selling Stockholders to the Company set forth in the Agreement, 10% of the Shares are and will be held in escrow until no later than June 7, 1995.

The Shares may be sold from time to time directly by the Selling Stockholders. In the alternative, the distribution of the Shares by the Selling Stockholders may be effected from time to time by underwriters

10


who may be selected by the Selling Stockholders and one or more other broker-dealers, in one or more transactions (which may involve crosses and block transactions) on the New York Stock Exchange or other exchanges, in special offerings, exchange distributions or secondary distributions pursuant to and in accordance with the rules of such exchanges, in the over-the-counter market, in negotiated transactions or otherwise, at market prices prevailing at time of sale, at prices related to such prevailing market prices or at negotiated prices. In the event that such underwriters or broker-dealers agree to sell the Shares, they may do so by purchasing the Shares as principals or by selling the Shares as agents for the Selling Stockholders. Underwriters selected by the Selling Stockholders, and any such other broker-dealer, may receive compensation from the Selling Stockholders in the form of underwriting discounts, concessions or commissions and may receive commissions from purchasers of the Shares for who they may act as agents. If underwriters who may be selected by the Selling Stockholders, and any such other broker- dealer, purchase the Shares as principals, they may effect resales of the Shares from time to time to or through other broker-dealers, and such other broker-dealers may receive compensation in the form of concessions or commissions from the Selling Stockholders or purchasers of Shares for whom they may act as agents. Corning has agreed to indemnify the Selling Stockholders, against certain liabilities, including liabilities under the Securities Act, and to pay the expenses of registering the Shares for offering and sale to the public under the Securities Act.

Information as to whether underwriters who may be selected by the Selling Stockholders, or any other broker-dealer, is acting as principal or agent for the Selling Stockholders, the compensation to be received by underwriters who may be selected by the Selling Stockholders, or any broker-dealer, acting as principal or agent for the Selling Stockholders and the compensation to be received by other broker-dealers, in the event the compensation of such other broker-dealers is in excess of usual and customary commissions, will be disclosed in a prospectus filed pursuant to Rule 424(b) under the Securities Act, or in a supplement to this prospectus filed pursuant to Rule 424(c) of the Securities Act to the extent required.

The Company has agreed with the Selling Stockholders to maintain the continuous effectiveness of the Registration Statement (of which this Prospectus is a part) during the period commencing on the date the Registration Statement is declared effective and ending on the second anniversary of the effective date of the Registration Statement or such shorter period which will terminate when all the Shares have been sold pursuant to the Registration Statement.

INFORMATION NOT REQUIRED IN PROSPECTUS

Item 14. Other Expenses of Issuance and Distribution.
The following table sets forth the estimated expenses to be incurred in connection with the distribution of the securities to be registered, other than underwriting discounts and commissions. The Company will pay the following expenses:

Registration Fee         $43,382
Legal Fees                $ 3,000
Printing Fees             $ 2,000
Accounting Fees           $12,000
Miscellaneous             $ 1,618
Total                     $62,000

Item 15. Indemnification of Directors and Officers.
Under the NYBCL, a corporation may indemnify its directors and officers made, or threatened to be made, a party to any action or proceeding, except for stockholder derivative suits, if such director or officer acted in good faith, for a purpose which he or she reasonably believed to be in or, in the case of service to another corporation or enterprise, not opposed to, the best interests of the corporation, and, in criminal proceedings, had no reasonable cause to believe his or her conduct was unlawful. In the case of stockholder derivative suits, the corporation may indemnify a director or officer if he or she acted in good faith for a purpose which he or she reasonably believed to be in or, in the case of service to another corporation or enterprise, not opposed to the best interests of the corporation, except that no indemnification may be made in respect of (i) a threatened action, or a pending action which is settled or otherwise disposed of, or (ii) any claim, issue or matter as to which such person has been adjudged to be liable to the corporation, unless and only to the extent that the court in which the action was brought, or, if no action was brought, any court of competent jurisdiction, determines upon application that, in view of all the circumstances of the case, the person is fairly and reasonably entitled to indemnity for such portion of the settlement amount and expenses as the court deems proper.

Any person who has been successful on the merits or otherwise in the defense of a civil or criminal action or proceeding will be entitled to indemnification. Except as provided in the preceding sentence, unless ordered by a court pursuant to the NYBCL, any indemnification under the NYBCL pursuant to the above paragraph may be made only if authorized in the specific case and after a finding that the director or officer met the requisite standard of conduct by (i) the disinterested directors if a quorum is available, (ii) the board upon the written opinion of independent legal counsel or (iii) the stockholders.

The indemnification described above under the NYBCL is not exclusive of other indemnification rights to which a director or officer may be entitled, whether contained in the certificate of incorporation or by-laws or when authorized by (i) such certificate of incorporation or by-laws, (ii) a resolution of stockholders, (iii) a resolution of directors or (iv) an agreement providing for such indemnification, provided that no indemnification may be made to or on behalf of any director or officer if a judgment or other final adjudication adverse to the director or officer establishes that his or her acts were committed in bad faith or were the result of active and deliberate dishonesty and were material to the cause of action so adjudicated, or that he or she personally gained in fact a financial profit or other advantage to which he or she was not legally entitled.

The foregoing statement is qualified in its entirety by reference to Sections 715, 717 and 721 through 725 of the NYBCL.

Article VIII of the registrant's By-Laws provides that the registrant shall indemnify each director and officer against all costs and expenses actually and reasonably incurred by him in connection with the defense of any claim, action, suit or proceeding against him by reason of his being or having been a director or officer of the registrant to the full extent permitted by, and consistent with, the NYBCL.

The directors and officers of the registrant are covered by insurance policies indemnifying them against certain liabilities, including certain liabilities arising under the Securities Act, which might be incurred by them in such capacities.

Item 17. Undertakings.
The Company hereby undertakes (1) to file, during any period in which offers or sales are being made, a post-effective amendment to this registration statement; (i) to include any prospectus required by Section 10(a)(3) of the Securities Act of 1933; (ii) to reflect in the prospectus any facts or events arising after the effective date of this registration statement (or the most recent post-effective amendment thereof) which, individually or in the aggregate, represent a fundamental change in the information set forth in the registration statement; and (iii) to include any material information with respect to the plan of distribution not previously disclosed in this registration statement or any material change to such information in the registration statement; provided, however, that paragraphs (1)(i) and (1)(ii) do not apply if the information required to be included in a post-effective amendment thereby is contained in periodic reports filed by the Company pursuant to Section 13 or Section 15(d) of the Securities Exchange Act of 1934 that are incorporated by reference in the registration statement; (2) that, for the purpose of determining any liability under the Securities Act of 1933, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof; (3) to remove from registration by means of post-effective amendment any of the securities being registered which remain unsold at the termination of the offering; and (4) that, for purposes of determining any liability under the Securities Act of 1933, each filing of the Company's annual report pursuant to Section 13(a) or Section 15(d) of the Securities Exchange Act of 1934 (and, where applicable, each filing of an employee benefit plan's annual report pursuant to

14


Section 15(d) of the Securities Exchange Act of 1934) that is incorporated by reference in this registration statement shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

Insofar as indemnification for liabilities arising under the Securities Act of 1933 may be permitted to directors, officers and controlling persons of the Company pursuant to the foregoing provisions, or otherwise, the Company has been advised that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in such Act and is, therefore, unenforceable. In the event a claim for indemnification against such liabilities (other than the payment by the Company of expenses incurred or paid by a director, officer or controlling person of the Company in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the Company will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in such Act and will be governed by the final adjudication of such issue.

Section 1361 of the Internal Revenue Code) or a partnership attributable to a taxable period ending on or before the Closing Date and arising solely from the reallocation of income or deductions between such entity member and another entity member of the MML Group which is not an S corporation or a partnership, shall be for the credit of Corning, but only to the extent that such refund (i) is not attributable to a timing difference that will decrease the taxes of an entity member of the MML Group in the same year or a later year, or (ii) is not offset by a corresponding increase in the taxes of an MML Group Shareholder of another member of the MML Group, which is an S corporation or a partnership. Any refund payable to Corning pursuant to this Section, shall be paid promptly by the respective MML Group Shareholders.

(b) Any deficiencies or assessments for additional income taxes against an MML Group Shareholder attributable to an entity member of the MML Group which is an S corporation or a partnership, for a taxable period ending on or before the Closing Date and arising solely from (i) the reallocation of income or deductions between such entity member and another entity member of the MML Group which is not an S corporation or (ii) the capitalization of a previously deducted item by an entity member of the MML Group, which is an S corporation or a partnership, shall be the responsibility of Corning, except to the extent such deficiency or assessment (A) is not attributable to a timing difference that will decrease the taxes of another entity member of the MML Group in the same year or in a later year or (B) is offset by

42


a corresponding decrease in the taxes of an MML Group Shareholder of another member of the MML Group which is an S corporation or a partnership. In the case of such a deficiency or assessment, Corning shall distribute to the appropriate MML Group Shareholders the shares due them, determined by dividing the amount of such tax deficiencies or assessments (including any interest thereon, if any) by the Value of a Share of Common Stock as defined in Section 2.3(b) of the Escrow Agreement.

(c) Corning, on the one hand, and the MML Group Shareholders, on the other hand, agree to give prompt notice to each other of any proposed adjustment to taxes for periods ending on or prior to the Closing Date or any pre-Closing partial period. Corning and the MML Group Shareholders shall cooperate with each other in the conduct of any audit or other proceedings involving the acquired corporations, and each may participate at its own expense, provided that the applicable MML Group Shareholders shall have the right to control the conduct of any such audit or proceeding for which they agree that any resultant taxes are covered by the indemnity set forth in this Agreement. Notwithstanding the foregoing, the MML Group Shareholders may not settle or otherwise resolve any claim, suit, or proceeding without the consent of Corning during the period that the indemnity in this Section 8.14 remains outstanding, such consent not to be unreasonably withheld.

September 29, 1994

To the Board of Directors of Corning
Incorporated

Dear Sirs:

As General Counsel for Corning Incorporated (the "Company"), I have participated in the preparation of a Registration Statement on Form S-3 (the "Registration Statement") being filed today with the Se curities and Exchange Commission with respect to 4,451,197 shares of the Company's Common Stock, $.50 par value (the "Common Stock"), issued on June 7, 1994 to the shareholders of Maryland Medical Laboratory, Inc., a Maryland corporation; Maryland Medical Data, Inc., a Maryland corporation; P harmaceutical Laboratory Services, Inc., a Maryland corporation; Passen Professional Service, P.A., a Maryland professional corporation and Podiatric Pathology Laboratories, Inc., a Maryland corporation (collectively the "MML Group") pursuant to the terms of the Agreement and Plans of Merger dated as May 3, 1994 between the Company, the MML Group and the shareholders of the MML Group (the "Agreement").

In this capacity, I have examined signed copies of the Registration Statement to be filed with the Commission today. I have also examined the originals, or copies identified to my satisfaction, of such corporate records of the Company, such other agreements and instruments, certificates of public officials, officers of the Company and other persons, and such other documents as I have deemed necessary as a basis for the opinions hereinafter expressed. Based upon the for egoing and having regard for such legal considerations that I deem relevant, I am of the opinion that:

1. The Company has been duly incorporated and is validly existing under the laws of the State of New York;

2. The execution and delivery on behalf of the Company of the Agreement has been duly authorized by all proper corporate proceedings of the Company and constitutes a legal, valid and binding instrument of the Company; and

3. The 4,451,197 shares of Common Stock of the Company issued pursuant to the terms of the Agreement are validly issued, fully paid and nonassessable.

I hereby consent to the use of this opinion as an exhibit to the Registration Statement and to the use of my name in "Legal Opinions" in the related prospectus.

Very truly yours,


/s/ William C. Ughetta
